Bangkok Post. A Bangkok city bus converted to run on compressed natural gas exploded as the driver was filling its fuel tank. The explosion damaged five vehicles and injured a worker at the station.
Police said that the records for the vehicle indicated that the fuel tank did not meet minimum standards for the conversion. The gas cylinder installed on the bus was part of a shipment imported from China as used products, and may have been too old for use, police said. It burst under the pressure, they said.
Police also said the bus records indicated that the operator of the bus had not received permission from Bangkok or Land Transport Department officials to convert the vehicle from diesel to gas. The rapid rise in the price of fuel has impelled many drivers and commercial operators to rush to convert petrol and diesel vehicles to various types of gas. This has cause some chaos, as unqualified mechanics and garages have cashed in on demand by providing unstable and sometimes dangerous conversions.
